[Screening and management of visual disorders in adolescents: impact on social inequality]

A retrospective cohort study was carried out on a sample of 2625 Belgian's children, examined at 12 and 15 year, to analyze the impact of school visual screening on social inequalities for visual acuity. Although uncorrected visual acuity decreased with increase in social class, visual acuity tested with the child's usual correction increased with social class. This social inequalities became more pronounced 2 years after the school visual screening. The lack of accessibility at some levels of health care cancels the reduction of inequalities expected from the school screening.
